Whoa! You can't buy your own item.



The Rapidstrike is the cornerstone of modern Nerf - a fully automatic, highly reliable and easy-to-use blaster. This kit provides the basic parts necessary to upgrade your motors and wiring for maximum foam firepower.

Available in three variations:
* Low Power - our 3D printed plate, microswitches and the 18 AWG wire, heatshrink and battery connector required to replace the original wiring with wiring suitable for most reasonable upgrade motors (eg: MTB Rhino).
* High Power - our 3D printed plate, microswitches and the 16 AWG wire, FET, diode, resistor, heatshrink and battery connector required to replace the original wiring with high power wiring, suitable for large 180 motors, or neo-magnet motors.
* No Wire - our 3D printed plate, and the microswitches needed to replace the stock wiring with wiring of your choice (you are responsible for supplying all other components. Only select this if you know what you're doing)

If you're new to upgrading electric blasters, you may wish to start with the Stryfe, or similar, as it's much simpler.

We offer high and low power versions of this product because different motors have different needs and the cost difference is large enough for it to be economical. If you are unsure, we recommend the low power option with suitable 130 motors (eg: MTB Rhino) for ease of installation and because that makes it harder to reach muzzle velocities in excess of 130 feet per second (which is a limit that many UK clubs set as then the kinetic energy of a dart is not high enough to cause permanent eye injury). We always recommend eye protection, regardless.
